Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components are included in compact wearable devices, then device functionality is enhanced, but component performance is limited due to space constraints
Solution Approach 1:
The antenna feed assembly is nested within the device housing, with the conductive grounding component at least partially surrounding the component housing. This nested configuration allows multiple components (antenna feed, grounding component, component housing) to occupy overlapping spatial volumes, maximizing space utilization while maintaining optimal performance of each component.
Solution Approach 2:
The conductive grounding component extends in multiple dimensions, at least partially surrounding both the first major surface and second major surface of the component housing. This multi-dimensional arrangement allows the grounding component to provide comprehensive electrical grounding and interference shielding without increasing the overall device footprint, thereby maintaining component performance in a compact form factor.
2Reliability
If antenna feed assemblies are added to improve antenna performance, then antenna efficiency is enhanced, but device complexity increases
Solution Approach 1:
The conductive grounding component serves multiple functions simultaneously: it provides electrical grounding for the antenna feed assembly, acts as a shield against electromagnetic interference, and structurally surrounds the component housing. By merging these functions into a single component, the design enhances antenna efficiency without proportionally increasing device complexity.
Solution Approach 2:
The conductive grounding component is designed as a multi-functional element that performs grounding, shielding, and structural support functions. This universal component approach allows the device to achieve improved antenna performance through a single integrated component rather than requiring separate components for each function, thereby limiting the increase in device complexity.
3Object-affected harmful factors
If conductive grounding components surround component housing, then electromagnetic interference is reduced, but manufacturing complexity increases
Solution Approach 1:
The conductive grounding component is nested within the device housing and surrounds the component housing, creating a nested structure that provides electromagnetic shielding. This nested configuration allows the grounding component to be integrated into the existing device architecture without requiring separate manufacturing processes or additional assembly steps, thereby limiting the increase in manufacturing complexity while effectively reducing electromagnetic interference.
